CHRISTOPHER POOR AND CHARLES VOULF, OF BLACK BU ER, NEW YORK.

BALlNG-PRESS.

EJPECIPICATION forming part of Letters Patent No. 362,994, dated May 17, 1887.

Serial No. 200,110. (No model.)

To aZZ whom, it may concern:

Be it known that we, CHRISTOPHER Poon and CHARLES WoULr, citizens of the United States, residing at Black River, in the county of Jefferson and State of New York, have invented new and useful Improvements in Ballug-Presses, of which the following is a specification.

This invention has for its objects to provide novel means for operating the platen of a press for baling hay, straw, cotton, or other material; to provide novel means for increasing the power and pressure of the platen as the material is being compressed, and to provide novel means for moving the platen by a capstanwheel or horse-power mechanism.

The objects of our invention are accomplished in the manner and by the combination of devices hereinafter described and claimed, reference being made to the accompanying drawings, in whieh Figure 1 is a front elevation of a balingpress embodying our invention; Fig. 2, a (letail inside View of the case containing the gearing which directly engages the lifting rackbars; Fig. 3, a detail plan view of the sweep and wheel devices for operating the cables'and imparting motion to the gearing which engages the raek-bars, and Fig. 4 a detail side elevation of a pair of pulleys for operating the gearing in the case through which the rackbar passes.

In order to enable those skilled in the art to make and use our invention, we will now describe the same in detail, referring to the drawings, wherein- The numeral 1 indicates the base-frame of a baling press, such as has vertical cornerposts 2, an opening and closing front door, 3, hinged at 2, and having hinged supportinglegs 3, and secured by pivoted clevises 4, a head-block, 5, secured by clevises 6, and a side, 7, held by a cam-lever, 8, which parts can be opened to gain access to the formed bale, and for other purposes. The beam 9, which carries the usual platen, is movable upward, to press the material between such platen and the top 10 of the press, said top being sustained by the head-block. The construction of these parts is similar to that in balingpresses which are well known, and a further detailed description is deemed unnecessary. They may all be constructed in any manner suitable for the conditions required.

Our invent-ion resides particularly in the novel means provided for raising andlowering the platen-carrying beam and other features, which will be now set forth.

At each end of the press-frame is aplatform or shelf, 11, supported by the extended ends of longitudinal side beams, 12, and transverse end bars, 13, and on each platform or shelf is securely fixed a malleable iron or other case, 14, containing the gearing, which engages and operates the lifting rack-bars 15, which connect with the projecting ends of the platencarrying beam through the medium of links 16, or otherwise. Through a slot in the rear side, 17, of each case 14 projects a frictionroller, 18, supported by suitable bearings, 19, and against which the straight rear faces of the rackbars 15 bear, for the purpose of pre venting the said bars from grinding out or wearing the rear walls of the cases and for reducing friction, so that the bars can freely rise and fall.

In each case 14 are journaled three shafts, 20, 21, and 22, the first mentioned being the main driving-shaft and carrying a pinion, -3, and ratchet-wheel 24, said pinion meshing into a gear-wheel,25,on the shaft 21. A pinion, 26, on the latter shaft meshes into a gear-wheel, 27, on the shaft 22, and a pinion, 28, on the latter directly engages the rack-teeth on the lifting-bars. The rotation of the shafts 20 in the direction of the arrow (see Fig. 2) will through the aforesaid gearing act upon the rack-bars to elevate them, thereby lifting the platen carrying beam to effect the pressing of the material in the press into a bale.

To prevent back movement of the gearing during the operation of the press or at any other time desired, a catch-pawl, 29, is pivoted in the case to engage the ratchet-wheel 24, the handle ofthe pawl extending through the slot 30 in the front side of the ease, whereby it can be operated to release the ratchet-wheel and permit backward movement of the gearing to lower the rack-bars.

To a projecting part of the main shaft 20 of each case are keyed two flanged pulleys, 31 and 32, of unequal diameter, the former in IOU . practice being about sixteen inches in diame- 'ter, while the outer one, 32, is about thirtysix inches in diameter. The inner flange of the pulley 32 is provided with a notch, 33; and

.a hollow spindle, 42, upon which revolves a capstan-wheel, 37, having radial arms 38, connecting the hub with the flanged rim. A sweep, 39, is mounted on a bolt, 42, extending through the hollow spindle,andprovided with a washer and nut, said sweep carrying a pivoted hook, 41, for engaging any one of the radial arms 38. \Vhen the wheel is rotated in the direction of the arrow, the cables 34 are wound thereupon, and the power of the cables first acts on the small pulleys 31, thereby rotating them and revolving the main shafts 20 of the gearings in the cases 14, to elevate the rack-bars with the platen-carrying beam. The sweep and capstan-wheel work independent of each other, but move together when the hook 41 engages one of the radial arms of the capstan-wheel. The cables act on the small pulleys until the pressure becomes too great, when the power is'immediately transferred to the large pulleys 32, which occurs when the power must be increased above that afforded by the small pulleys as the bale is being formed. In other words, as the hay or other material is light or loose the cables operate on the small pulleys, thus affording speed in lifting the platen carrying beam; but as greater force is required the power of the cables shifts from the small to the large pulleys. By this means the power and pressure of the platen are ill-- creased as required during the compression of the material in the press.

The power can be regulated by winding more or less of the cables around the small pulleys. The sweep is carried around by one or more animals hitched to the outer end thereof in any suitable manner; but obviously the sweep can be operated by attendants.

The press is built of timber stiff and rigid,

and in such manner that it can be conveniently and rapidly constructed, and, if desired, b moved with little trouble.

Mounted on the sweep 39 is an arm, 40, for the attachment of an ordinary lead-rope.

Having thus described our invention, what we claim is e 1. The combination, with the platen-carrying beam and the lifting rack-bars of a baling-press, of the end cases on the press-frame, gearings in said cases engaging and operating the lifting-bars,'two pulleys of unequal diameters on the main shafts, cables engaging the pulleys, and a capstan-wheel for operating the cables, substantially as described.

2. The combination, with the platen-carrying beam and the lifting rack-bars of a baling-press, of the end cases on the press-frame, gearings in said cases engaging the lifting-bars, two flanged pulleys of unequal diameter secured to the mainshafts, 'the largest pulley having a notch in one flange, cables engaging the pulleys, a capstan-wheel for operating the cables,'and a sweep having means to engage and disengage the capstan-wheel,substantiall y as described.

3. The combination, with the platen-carrying beam and lifting rack-bars of a balingpress, of the end cases on the press-frame,

gearings in said cases for operating theliftingbars, two pulleys of unequal diameter mounted on each main shaft, cables engaging the pulleys, a capstan-wheel for operating the cables, and snatch-blocks or guides for the cables, substantially asdesc-ribed- 4. The combination, with the platen-carrying beam'and lifting-bars of a baling-press, of gearing for operating the lifting-bars, two flanged pulleys of unequal diameter mounted on the main shafts, and each pulley of the greatest diameter having a notch at the periphery of its inner flange, cables engaging the pulleys and passing through the notches in said flanges, and meansfor winding and unwinding the cables, substantially as described.

In testimony whereof we affix our signatures in presence of two witnesses.

CHRISTOPHER POOR. CHARLES WOULF.
